Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed November 12, 1917. Serial No, 201,707.

To all 'whom t may conrrnm Be it known that l, CHARLES HOWARD FUNKEY, a citizen of the United States, residing at Ramsay, in the county of Gogebic, State of Michigan, have invented a new and useful Excavating-Machine for Mining; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved excavating or shoveling machine for mining urposes, and particularly adapted for use in tunnels 'or drifts, for the purpose of removing the drift heading.

One of the objects of the invention is the provision of an excavating or shoveling machine, in which the digger or shoveling member is given a backward and forward movement, and also a rocking movement as the digger or,shoveling member reciprocates, so that after the member moves forward and excavates the drift heading, it may return, and dump the excavated material onto a conveyer, which carries the material upwardly and rearwardly to the rear of the tunnel and behind the machine, where it can be removed.

A further object of the invention is the provision of means, whereby the shoveling or digger member proper is given a slight oscillatory movement independent of the reciprocating and oscillatory movement of its shank, so that the shoveling and dumping of the material may be more eficiently performed.

A further object of the invention is the provision of means, whereby the mounting for the digger or shoveling member may be given a slight horizontal oscillatory movement, whereby said member may be moved laterally.

A further object of the invention is the provision of a conveyer to carry the excavated material rearwardly, in combination with means on the forward end of the conveyer to receive the excavated material from the shovel, whereby the material may feed onto the conveyer.

A further object of the invention is the provision of an improved, simple, efficient and inexpensive construction of machine of this kind, which consists of few parts, and is therefore durable and practical.

The invention comprises further features and combination of parts as hereinafter set forth, shown in the drawings and claimed.

In the drawings z- Figure 1 is a view in side elevation of the improved excavating or shoveling machine constructed in accordance with the invention.

Fig. 2 is a view in front elevation, the motor used for reciprocating the shovel or digger member bein omitted.

Fig. 3 is a vertical sectional view on line 3-3 of Fig. 1.

Fig. 4 is a plan view, showing parts in section.

Fig. 5 is a sectional view on line 5-5 of Fig. 4, showing parts in elevation, and showing the shovel or digger member as having been receded and disposed in dumping position over the lower end of the conveyer.

Fig. 6 is an enlarged detail view, showing the connection or coupling between parts of an extension to the conveyer frame.

Referring more especially to the drawings 1 designates the main frame of the improved excavating or shoveling machine. The sides 2 of the frame are constructed of channel irons, said sides 2 being connected by the cross pieces 3 and 4, and bolted or otherwise secured at 5 to the u per portions of the forward ends of the sies is a substantially U-shaped or arched frame 6, the sides 7 of which are angular in cross section, and the upper portions of the sides 7 of said frame 6 are integrally connected by the lower portion 8 of a turn table, which is preferably elliptical in plan view, as shown in Fig. 4. Suitable bearings 9 for the front and rear axles 10 and 11 are bolted or otherwise secured to the under parts of the channel iron sides 2 of the frame 1, and carried by the axles 10 and 11 are suitable wheels 12, whereby the shoveling or excavating machine is portable upon suitable rails 13. A suitable conveyer frame 14 has its side channel irons 15 braced by the members 16 between the sides 7 of the frame 6 at the forward part of the frame of the machine. The rear upper ends of the channel iron sides 14 of said conveyer frame are mounted upon a shaft 17, which in turn is mounted in suitable bearings of the uprights 18, which rise upwardly from the rear ends of the side channel irons 2 of the framev 1. A second shaft or rod 19 has its ends also mounted. in bearings of the uptrights 18. Loosely mounted upon the sha s or rods 17 and 19 are suitable rollers 20 and 2l. Mounted in suitable bearings 22 (which are secured to the under portions of the forward ends of the side channel irons of the conveyer frame) is a shaft 23, on which a roller 24 is mounted. The conveyer frame at its rear upper end has an extension Conveyer frame 25, the sides of which are also constructed of channel irons, the forward ends of which are pivotcd at 26 to the rear upper ends of the channel iron sides of the main conveyer frame. Where the sides of the extension conveyer frame are pivoted to the sides of the main frame, the iianges of said channel iron of the extension frame are cut away, as shown clearly in Fig. 6. Secured at 27 to the under portions of the rear end of the sides of the extension frame are guide brackets 28, in which the bearing blocks 29 are slidably and adjustably mounted. Mounted in bearings of said blocks 29 is a shaft 30, to which a roller or drum 31 is keyed as shown at 32. On one end of the shaft 30 a sprocket Wheel. 33 is fixed. Any conventional form of motor, such as shown at 34, is mounted upon the cross piece 4 of the frame 1, and its driving shaft 35 has a sprocket 36 keyed thereto. A sprocket chain 37 passes about the sprockets 36 and 33, whereby motion may be imparted to the shaft 30 and consequently to the roller 31, which in turn iniparts movement to the conveyer belt 38 (which travels about the rollers or drums 24 and 31) in the direction of the arrow cr, whereby the excavated material may be conveyed upwardly and rearwardlyT and allowed to dump to the rear of the machine. The upper and lower portions of the conveyer belt engage and travel on the rollers 2O and 2l. Suitable screws 39 are mounted in the bracket member 28 and bear against the bearing blocks 29, whereby as said screws are turned in one direction or the other the bearing blocks may be adjusted. The adjustment of said bearing blocks will loosen or tighten the conveyer belt. Pivoted upon ears 40 of the sides of the extension of the conveyer frame are supporting braces 41, which have series of notches 42, any two register-in notches of which may engage the axially allned headed lugs 43 (whlch project outwardly from the uprights 18), so as to support the eonveyer extension frame in different adjusted positions. Extension strips are riveted or otherwise secured at 44 to the upper edge portions of the sides 15 of the conveyer frame 14. These extension strips 45 have their lower forward ends connected by a transverse piece or plate 46, which is disposed atan angle to the conveyer, and rearwardly of this transverse piece or plate, the upper edges of said strips 45 have extensions 47. These extensions 47 are adjacent the sides of the frame 6, and

are substantially under the arch of said frame. The sides of the conveyer extension have riveted thereto as shown at 48 extension strips 49, which are similar to the upper rear portions of said strips 45. A suitable housing 50 has its lower portion provided with the upper turn table section 51, which is substantially elliptical, correspond ing to the turn table section `8. A suitable king pin 52 passes through the two turn table sections 8 and 51, and the lower end of its shank has a cotter pin 53, whereby the housing 50 is held pivotall su ported on the turn table section 8. he ousing 50 is rectangular in cross section, and may be of the general shape as shown in Figs. 1 and 5 in side elevation. The housing is open at its forward and rear ends, and has a top wall 54. Connecting the sides of the housing is a transverse piece or support 55, on which a conventional form of motor 56 is supported. The drive shaft 57 of the motor is provided with a Worm 58. This worm 58 meshes with the worm wheel 59, which is mounted upon the upper end of a shaft 60. Projecting from and secured to one of the side walls of the-housing 50 as shown at 61 is a bracket arm 62, in a bearing of which the shaft 60 is mounted, and the lower end of the shaft has a bevel gear 63. An arm 64 extends forwardly from the bearing 65 of said bracket 62, and curves under the bevel gear 63 and terminates in a bearing66. Secured at 67 tothe outer walls of the housing 50 are bearings 68 for the reception of the reduced ends 69 of the axially alined shaft sections 70 and 71, which also extend through the walls of said housing. The inner adjacent ends of said shaft sections 70 and 71 are mountedin the bearing 66. Keyed upon the shaft Sections as at 72 near their adjacent ends are beveled gears 73 and 74, with which the bevel gear v63 meshes, as shown clearly in Figs. 2, 3-and 5. Loosel mounted upon the shaft sections 7() and 71 adjacent the inner surfaces of the side walls of said housing are spur gears 75 and 76, the adjacent faces of which are rovided with tapel-ing clutch depressions 7 and 78. Keyed at 79 to the shaft sections 70 and 71 are clutch members 80 and 81, which are tapered to correspond with and engage the clutch depressions 78, when the clutch members 80 and 81 are accordingly moved. The clutch members proper 8O and 81 are each constructed in two sections 82, and cach section is separately keyed as at to the shaft section 71, while the operating sleeves 83 and 84 are keyed at 79 to the 4shaft sections. The clutch operating sleeves 84 and 83 are provided with ears `86, to which the links 87 are pivotally connected. The links 87 are in turn pivoted at 88 in depressions-89 of the clutch sections 82. The clutch opershovel.

ating sleeves 83 and 84 are rovided with spaced integral collars 90, an 1n the spaces between said collars suitable forked levers (not shown) may engage, for shiftin the sleeves 84 and 83 toward and from the c utch sections 82. It is to be observed that when the clutch sleeve 83 is moved outwardly thc clutch sections 82 of the clutch 80 are moved in frictional contact with the tapering depression 77 of the spur gear 75, which will impart motion to the gear in the direction of the arrow b, since the shaft 60 is rotating continuously in one direction. When the clutch is released from its depression 77 and the clutch 81 is moved in engagement with the depression 78 of the gear 76, by moving the sleeve 84, said spur gear 76 will be rotated in the direction of the arrow c. It is to be noted that the spur gears 75 and 76 may be operated in opposite directions. Carried by the upper surface of the turn table section 51 of the housing are bearings 91, in which the end portions of a shaft 92 are mounted. The opposite ends of the shaft 92 are provided with spur gears 93 and 94, which are smaller in diameter and mesh with the sp-ur gears 75 and 76. By this arrangement it is to be noted when the gear 75 is rotated in the direction of the arrow b, the shaft 92 will rotate in one direction, and when the gear 76 is operated in the direction of the arrow c, the shaft 92 will rotate in the opposite direction. Mounted centrally on the shaft 92 and keyed to rotate therewith as shown at 95 is a pinion 96, and arching the pinion 96 is a guide 97, for the shank 98 of the shovel 99. The shovel 99 has its sides pivotally united as at 100 to said shank 98. In fact the forks 101 (which consist of metallic strips or straps, secured at 102 to the shank 98) are pivotally united to the sides of the This shank 98' is provided with rack teeth 103, which mesh with the teeth of the pinion 96, in view of which, it is to be noted that when the shaft 92 is operated in one direction, for instance as may be operated by the gear 75 moving in the direction of the arrow Z), said shovel shank will move :forwardly in the direction of the arrow d as shown in Fig. 5. When the shaft 92 is operated in the reverse direction, as may be accomplished by the gear 7'6, the shovel shank may be reciprocated rearwardly. By these movements the shovel or digger may be given a forward and backward movement, 1n order to eXcavate the material on the forward movement, and convey the material rearwardly on the return movement. The guide 97 consists of the side pieces 104, which straddle the pinion 96, and the plate 105. In order that the side pieces of the guide may be pivoted on the shaft 92 suitable cap plates 106 arch upwardly and under the shaft 92, and are secured to the Said side ieces 104, by means of the staples 107, whic are secured in place by the nut 108. The cap plates 106 are grooved as at 109, as are also the edges of the side pieces 104, for the reception of the arches an-d the arms of said staples. By this construction of guide, it is to be noted that the shovel. shank is not only capable of a reciprocating movement but also capable of an oscillatory movement. Pivotally united at 110 to the upper portions of the sides of the housing on the rod 111 are links 112, there being a sleeve 113 on thc rod 111, to hold the links separated and adjacent the side walls of said housing. These links 112are in turn pivoted at 114 to the links 115, which in turn are pivotally connected at 116 outside of said forks 101. Links 117 are pivoted on the ends of a rod 118, which passes through the lower rear ends of the links 115, there being a sleeve-119 between the two links 115, to hold them equally spaced. Suitable nuts 120 are threaded on the ends of the rod 118 to hold the links 117 in place. The links 117 are in turn pivoted lat 121 to the sides of the shovel or digger 99, which is open at its forward and rear end, whereby the material may be shoveled through the forward end and dumped from its rear end. The forward edge of the shovel or digger is provided with suitable teeth 122, in order to dig into and break up the material to be excavated. "When the scoop or shovel moves forward, the particular link connections between the forks, the shovel and the housing causes the shovel to be directed. downward and into the drift heading, when the shovel is bodily lowered, by means of the lever 128, as shown clearly in Fig. 1. When the shovel is moved rearwardly and upwardly, the shovel is given a tilting movement independently of the lifting and re ciprocating movement of the shank or beam of the shovel, whereby the material which is excavated may be dumped onto the plate 46, so that the material may be carried upwardly and rearwardly on the coinveyer. The lever 123 is keyed at 124 tothe rod 11.1. A segment rack 125 is secured at 126 to one of the sides of the housing, and the lever moves between the segment rack and the housing. A suitable dog 127 is mounted in a guide 128 of said lever. A rocking cross link 129 is pivoted at 130 to the lever 123, and has one end pivoted at 131 to the dog 127. A link 132 is pivoted to the other end of said cross member at 133. The link 132 is in turn pivoted at 134 to an angular hand grip 135 which in turn is pivoted at 196 to said lever. By means of the dog 127, cooperating with the teeth of the segment, and the operating' means for said dog the lever 123 may be moved and held in different adjusted positions.. The upper turn table section 51 of the housm'g has its margnal edge provided with a groove 137, in which the opposite ends of a belt 138 are secured. This belt passes about the pulleys 139 which are journaled on the brackets 140, while the loop of said belt engages about the pulleys 141, which are mounted upon the studs 142. It will be observed that when one or the other of said pulleys 141, or the belt 138 is moved, the turn table section 51 and the housing may be rocked slightly on the lower turn table section. A beam 143 has its reduced ends 144 secured in the terminal bearings 145 of the upper forward ends of the braces or links 146, by means of the cotter pins 147. The lower ends of the braces or links 146 are pivoted at 148 to the angular brackets 149, which are secured at 150 to the upper portions of the side channel irons 2 of the frame 1. A second king pin 151 passes through the bracket strap 152 (which is secured as at 153 to the top of the housing 50) and through the beam or cross piece 143, and through the top of the housing an-d is held in place by a cotter pin 154. This second king pin is axially alined with the king pin 52, thereby steadying and reinforcing the housing when it rocks horizontally, whereby the shovel may bel manipulated to accommodate itself for the purpose of excavating. From the foregoing it may be seen that the gearing in the housing is operated to reciprocate the rack or beam 98, so as to impart a forward and backward movement to the shovel. However, in order to regulate the position of the arc in which the link 115 swings, the lever 123 may be adjusted in different positions. For instance by movin the lever 123 downwardly rocking the sha.

110 the arm 112 will be swung upwardly, changing the position of the ivo-t 114, 1n which case the link 115 swings 1n a different arc than that in which it moves when the parts are positioned as shown in Fi 1. A reverse movement of the lever 123 wi l lower the pivot 114. However, when the rack or beam 98 is being reciprocated to operate the shovel or scoop toexcavate, thescoop on the forward movement of the beam or rack 98 will enter the embankment, and on the rearward movement of the beam 98, the scoop will maintain a substantially horizontal position, until it is over the portion 46 of the conveyer, then the scoop will tilt and dump the material onto the conveyer, in order to be conveyed upwardly and rearwardly.
